Answer 1

First define your button variables in your activity/fragment

Button button1;
Button button2;

In the onCreate (activity) or onCreateView (fragment) method, link the button objects to the buttons in your layout, and set their onClickListeners:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    button1= (Button) findViewById(R.id.button1);
    button1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            //do something
        }
    });
    button2 = (Button) findViewById(R.id.button2);
    button2.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            //do something else
        }
    });
}

Your layout file should then have something like this:
